I think it’s a good move. I also like the fact that they’ve flagged up that one of their reviewers of colour didn’t agree with the decision. Because guess what, not all people of colour hold exactly the same views on what’s racist and what isn’t, what with us all being different people and so forth 🙂 . Kirkus have made this decision to try it this way, and I think it’s a good one. It draws attention to the white default, and that’s a good thing, I think. If you can’t see the problem, you can’t start tackling it.
